This document describes the two types of nutrition in living things: 1) Autotrophic nutrition, where organisms produce their own food through photosynthesis or chemosynthesis. 2) Heterotrophic nutrition, where organisms obtain organic compounds from other organisms. Autotrophs like plants perform photosynthesis, while deep sea tube worms use chemosynthesis. Heterotrophs such as animals and protozoa cannot produce their own food and rely on consuming organic compounds produced by autotrophs.

Nutrition
Nutrients can be divided into micro and macro categories. Macro-nutrients include carbohydrates, proteins, and fats, which are required in large amounts and provide calories. Carbohydrates serve as the body's primary energy source and are made up of sugars, starches, and fiber. Proteins are made of amino acids and provide energy as well as building blocks for growth and repair.
Life Processes
This document provides an overview of various life processes including nutrition, respiration, transportation, excretion, and reproduction. It describes in detail the processes of nutrition, photosynthesis, respiration, and the human digestive and circulatory systems. For nutrition, it explains the different types of nutrients, the steps of digestion and absorption in humans, and photosynthesis in plants. For respiration, it discusses the gas exchange in animals and plants, and aerobic and anaerobic cellular respiration. It also provides a brief introduction to the transportation and circulation systems in humans.

Năng lượng Mới cho một nước Việt siêu hiện đại
Năng lượng Mới là gì?
Năng lượng Mới là một nguồn năng lượng chỉ được nghiên cứu nghiêm túc tại các trường đại học hàng đầu thế giới trong mấy năm qua. Nó không phải là năng lượng từ ánh sáng mặt trời, hay từ gió, hay từ chất thải nông nghiệp. Nó cũng không phải là năng lượng từ việc đốt than, dầu, hoặc khí. Nó không phải là thủy điện hay điện từ chất phóng xạ.
Năng lượng Mới khai thác các dao động điện từ tự nhiên trong chân không lượng tử để phát điện, chạy xe, và lọc nước biển. Nó có thể cho phép một tàu bay không bị ảnh hưởng bởi trọng lực Trái đất và như thế, nó có thể đạt vận tốc hàng chục nghìn km/giờ. Nó là một nguồn năng lượng vô tận và sạch sẽ. Và chi phí sử dụng năng lượng này thường rẻ hơn năng lượng hiện nay khoảng 90%.
Hãy tưởng tượng một thế giới không cần đến những mạng lưới điện vì mỗi hộ nhà và mỗi thiết bị gia dụng sẽ tự phát điện lực cần thiết từ chân không lượng tử. Việc trả tiền điện hàng tháng sẽ đi vào dĩ vãng. Hãy tưởng tượng một thế giới người tham gia giao thông đổ nước lã thay vì xăng để chạy xe. Đó chỉ là một vài ví dụ những gì chúng ta sẽ chứng kiến trong Thời đại Năng lượng Mới.
Energy
The document discusses energy and its sources, uses, and requirements by the human body. It defines energy and lists the main sources of energy as carbohydrates, proteins, and fats obtained through food. These macronutrients provide energy measured in kilojoules or calories. Different activities require different amounts of energy, and an individual's daily energy needs depend on factors like age, physical activity level, and health. The basal metabolic rate is the minimum energy needed to sustain vital body functions at rest.
Malnutrition on micronutrients
Micronutrients are essential elements required by organisms in small quantities to maintain health. Deficiencies of specific micronutrients like vitamins A, B1, C, and D can cause night blindness, beriberi, scurvy, and osteomalacia respectively. Malnutrition during early childhood can negatively impact intellectual development and perpetuate lasting damage. While Bangladesh has made progress in reducing stunting and undernutrition, continued efforts are needed to strengthen nutrition programs and meet national targets.
Nutrition - minerals
This document provides information about minerals found in the human body. It discusses major minerals like calcium, phosphorus, sodium, and potassium which are required in amounts greater than 100mg per day. It also discusses trace minerals like iron, iodine, and magnesium which are required in smaller amounts less than 20mg per day. For each mineral, the document outlines its sources, absorption, functions, requirements, deficiency disorders, and treatment where relevant. The document provides an overview of the essential roles various minerals play in bone formation, soft tissue maintenance, enzyme and hormone production, and other physiological processes in the human body.

Food production System
This document outlines standard operating procedures for food production systems including receiving, storing, thawing, preparing, cooking, hot and cold holding, cooling, reheating, displaying, and delivering food. It emphasizes the importance of temperature control and hygiene to prevent food contamination and the growth of microorganisms. Key steps include checking food temperatures, packaging, rotation and cleanliness during receiving, storage, preparation, cooking, holding, cooling and reheating. Personal hygiene and avoidance of cross-contamination are also consistently stressed.
Herbivore, carnivore and omnivore animals
There are three main types of animals: herbivores, carnivores, and omnivores. Herbivores get their energy from plants and grass. Carnivores get energy solely from eating other animals. Omnivores obtain energy from both plants and animals. All three types play important roles in ecosystems, and imbalances could disrupt entire food chains. Protecting ecosystems and reducing pollution will help ensure a healthy environment for all species.
Food production basics
This document provides an overview of the history and development of the food service industry. It discusses how quantity cookery originated over 1000 years ago to feed large groups. In the 18th century in France, food production was controlled by guilds that licensed specific food items. The first restaurant opened in Paris in 1765 called "restaurants" that served restorative soups. The French Revolution led to the proliferation of restaurants as chefs went into business for themselves. Over time, French cuisine became more elaborate and consisted of many courses, known as Grande Cuisine. Notable chefs like Careme and Escoffier further refined and codified culinary techniques. The document also discusses types of kitchens, kitchen brigade systems,
Micro organisms
Microorganisms are microscopic organisms that include bacteria, archaea, protozoa, fungi, algae, and some animals. They play important roles in environments and processes like decomposition, nutrient cycling, and carbon cycling. There are four main types of microorganisms: bacteria, archaea, protozoa, and viruses. Bacteria are prokaryotic microbes that have diverse shapes and live in many environments. Viruses can only replicate inside host cells and come in different shapes and sizes but are usually 100 times smaller than bacteria. Protozoa are unicellular eukaryotic organisms including some motile species. Microorganisms are also used in food production and have medical applications but some can cause diseases if
nutrition in plants
The document summarizes photosynthesis in plants. It describes how plants perform autotrophic nutrition by using carbon dioxide, water, and sunlight to produce oxygen and glucose through the processes of light and dark reactions in the chloroplasts. Photosynthesis occurs primarily in leaves, which have adaptations like thinness, large surface area, and stomata to facilitate gas exchange and maximize light absorption for efficient photosynthesis.
Plant nutrition
This document discusses plant nutrition and how plants obtain nutrients. It covers how plants make their own food through photosynthesis, using sunlight, carbon dioxide, water and minerals from the soil. Photosynthesis occurs in the leaves and uses chlorophyll to produce oxygen and "elaborated sap", the plant's food. This food is distributed throughout the plant via phloem vessels. The document also discusses plant respiration, growth, movement and perception of time.
Micro-oganisms
This document provides an overview of different types of microorganisms including bacteria, viruses, fungi, yeast, algae, protozoa. It discusses how some microorganisms can cause diseases like athlete's foot, tuberculosis, and chickenpox, but others can be useful in food production, cleaning waste, and creating antibiotics. It also profiles Alexander Fleming, the scientist who discovered the first antibiotic, penicillin, in 1928 and received the Nobel Prize for his work.
1.3 useful microorganism
Microorganisms play an important role in decaying dead organisms and enriching the soil. They break down complex compounds into simpler ones that plants can use. Herbivores rely on bacteria in their stomach to digest cellulose from plants. Certain bacteria also live in human intestines and help with digestion while destroying harmful microbes. Some microbes like Penicillium molds produce important antibiotics that can treat diseases. Genetically engineered bacteria can produce vaccines and insulin. Microbes are crucial in agriculture by releasing nitrogen that plants need and in various industries through fermentation processes.
Biodiversity and its Conservation
Biodiversity refers to the variety of life on Earth at all levels, from genes to ecosystems. High levels of biodiversity are important for ecosystem functioning and human well-being. However, biodiversity is being lost due to threats like habitat loss, overexploitation, pollution, and climate change. Conservation approaches include protected areas as well as international agreements like CITES and the Convention on Biological Diversity, which aim to protect threatened species and ecosystems.
Biodiversity powerpoint
Biodiversity refers to the variety of all life forms including plants, animals, microorganisms and their genes and ecosystems. It is important for human sustenance, health, well-being and enjoyment of life. However, biodiversity is threatened by habitat loss, invasive species, pollution, climate change and overconsumption. The loss of biodiversity can reduce ecosystem services and genetic diversity, compromising food security. Australia is taking steps to preserve biodiversity through programs, reserves, and acts aimed at conservation and education.

6570567 61 types-of-nutrition
Nutrition is the process by which organisms obtain energy from food for growth, maintenance and repair. There are two main types of nutrition: autotrophic and heterotrophic. Autotrophic nutrition involves synthesizing food from inorganic substances using light or chemical energy, such as photosynthesis in plants. Heterotrophic nutrition obtains energy by ingesting and digesting organic substances from other organisms, including holozoic nutrition by ingestion, saprophytism of decaying matter, and parasitism living in or on a host.
Tanuj kumar
Autotrophic and heterotrophic nutrition are the two types of nutrition. Autotrophic nutrition is the process by which autotrophs like plants produce their own food by taking in carbon dioxide and water and converting them into carbohydrates through photosynthesis using chlorophyll in the presence of sunlight. Heterotrophic nutrition involves organisms like animals depending on other organisms for food. Autotrophs include plants while heterotrophs include parasites, saprophytes, and humans.
Presentation2.pptx
Plants obtain nutrition through two main processes: autotrophic and heterotrophic nutrition. Autotrophic nutrition involves plants producing their own food from inorganic materials like carbon dioxide and water using photosynthesis. Heterotrophic nutrition involves organisms that cannot produce their own food and rely on consuming other organisms. There are also other modes of nutrition like parasitism, where an organism lives on or inside a host and feeds on it, saprophytism, where organisms break down dead and decaying matter to feed, and symbiosis, which refers to close relationships between two organisms of different species. Nutrients in soil are replenished through the addition of fertilizers and manures which contain important minerals for plants as well as nitrogen-
ENVIRONMENT SCIENCE AND STUDY OF BIODIVERSITY
The document defines key terms in ecology such as ecosystem, biome, producers, consumers, and decomposers. It explains that an ecosystem is a community of interacting organisms and their environment. Energy from the sun enters ecosystems during photosynthesis and is transferred between trophic levels as organisms consume each other. Nutrients cycle between biotic and abiotic components through decomposition. Producers, consumers, and decomposers all play important roles in the flow of energy and cycling of nutrients within ecosystems.
Energy Flow
Plants and other autotrophs are called producers because they convert inorganic material to organic compounds through photosynthesis. However, the term producer is misleading as plants produce organic compounds primarily for themselves, not just for animal consumption. Energy flows through ecosystems in a non-linear web, with only about 10% of energy transferred from each trophic level to the next as it is lost to the environment.
Energy flow in ecosystems
The document discusses energy flow through an ecosystem. It explains that grass, frogs, snakes, grasshoppers and hawks interact through a food chain where grass is eaten by grasshoppers which are eaten by snakes or frogs which may then be eaten by hawks. It also defines producers as organisms like grass that can produce their own food, consumers as organisms that cannot produce their own food and eat other organisms, and decomposers as organisms like bacteria and fungi that break down waste and dead organisms.
photosynthesis and chemosynthesis
Autotrophs can produce their own food through either photosynthesis or chemosynthesis. Photosynthesis uses sunlight as an energy source and occurs in plants, algae, and some bacteria containing chlorophyll. Chemosynthesis uses inorganic molecules from ocean vents as an energy source for bacteria. Heterotrophs cannot produce their own food and must obtain energy by consuming other organisms, breaking down food through cellular respiration.

classification of microorganism on the basis of their mode of nutrition.pptx
This document discusses the classification of microorganisms based on their mode of nutrition. It describes three main criteria for classification: carbon source, energy source, and electron source. Based on carbon source, microorganisms are either autotrophs, which produce their own organic carbon from inorganic carbon dioxide, or heterotrophs, which rely on other organisms for organic carbon. Based on energy source, they are either phototrophs, which use light as an energy source, or chemotrophs, which use chemical compounds. Based on electron source, they are either lithotrophs, which use inorganic electron donors, or organotrophs, which use organic electron donors. The document also lists the five main nutritional types

Biology teaching (ppt)
Nutrition is the process by which organisms take in food and convert it to energy and vital nutrients. There are two main types of nutrition - autotrophic and heterotrophic. Autotrophs like plants produce their own food through photosynthesis, using carbon dioxide, water and sunlight. Heterotrophs cannot produce their own food and depend on other organisms, either directly by eating plants or animals, or indirectly through food chains. Examples of heterotrophs include fungi, animals and humans.
Food chain
This document provides information about food chains. It begins by defining a food chain as a sequence of organisms through which energy flows as each organism obtains energy from the one below it in the chain. Producers, such as plants, are at the bottom of the food chain as they can produce their own food. Herbivores, as primary consumers, eat the producers. Carnivores eat herbivores or other carnivores. Omnivores both eat plants and other animals. Decomposers, like fungi and bacteria, break down waste and dead organisms, recycling nutrients in the ecosystem. The document includes examples of food chains and defines the roles of producers, consumers, and decomposers. It also

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Nutrition
- 1. Aim : How can we describe the types of nutrition in living things? Do now : 1. What is nutrition? 2. Why do living things need nutrition?
- 2. Nutrition : How an organism gets food ( nutrients, organic compounds ) and makes it available to the cells. Nutrients : useful portion of food: -sugar -amino acid -fat -starch Organic Compounds = FOOD!!!!!!
- 3. 2 TYPES OF NUTRITION 1. Autotrophic nutrition – Auto (self) trophic (refers to feeding and nutrition) “ Self feeding.” -Organisms that make their own organic compounds ex. Photo synthesis Chemo synthesis
- 4. a. Photosynthesis Photo (light) synthesis (creating, making) -Light is the source of energy for the production of food. -“Who?” ex. Plants
- 5. Autotrophs :
- 6. b. Chemosynthesis – Chemo (chemical) synthesis (creating, making) -Chemical activity is the source of energy for the production of organic compounds. Who? -organisms in environments that do not rely on the sun to make food. ex. Deep sea organisms
- 8. Chemosynthetic nutrition - Deep sea tube worms and arthropod
- 10. 2. Heterotrophic nutrition – Hetero: other trophic: (refers to feeding and nutrition) “ Fed by others.” - Heterotrophs: Organisms that eat organic compounds made by others. ex. Animals or animal-like protists called protozoa : amoeba, paramecium. Proto (first) zoa (animal, zoo)
- 11. Examples of heterotrophs paramecium
- 13. Obviously, a _________________ . heterotroph!
- 14. Are you a heterotroph? Summary : 2 types of nutrition on Earth: 1. Autotrophic - photosynthesis - chemosynthesis 2. Heterotrophic
